connection with the accompanyin drawings, the construction and operationof the invention will be readily understood without requiring n moreextended explanation.

Various changes in the form, proportion and the minor deieils ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claims.

Having thus described my invention, What I claim is:

1. in a tube bending tool, an anvil block, means whereby said block isheld in position for operation, a tube bending block adapted to co-actwith said anvil block, said tube bending block having a. recess in itsrear face to allow relative lateral movement of the block during theinsertion of the tube, a lever freely movable upon said bending block toactuate the tool, and means to prevent said block from slipping duringthe bending operation.

2. A tube bending tool comprising an anvil block having. formed thereina tube-receiving groove, av base plate upon which the anvil block issecured having its forward end bifurcated to form arms, the latterhavlongitudinul guiding grooves in their inner feces a clamping blockslidubly mounted between the arms of the base plate and provided withextensions whereby it is slid ably retained within said guiding grooves,a clamping lever pivotnlly mounted be tween said arms and having arounded end adapted to contact with the clamping block to move the someinto engagement with the tube to be bent, a bending block adapted toeoiiperute with the anvil block to bend said tube, and an operatinglever having u roller adapted to relatively engage the forward face ofthe bending block whereby the bending block is mo ed about the anvilblock.

in testimony who 'eo'f I have hereunto set my hand in presence of twosubscribing witnesses.
